HOW TO CONNECT

USB PORT

If your keyboard has a USB to Host port,

you will need a USB A to B cable. This cable is also referred to as a "printer cable" since it's used to connect printers to computers.

1. Plug the USB B end of the cable (squire-ish in shape) into the USB port on your keyboard. (If your keyboard has two USB ports: USB to Device and USB to Host, make sure to plug into the USB to Host port).

2. Plug the USB A end of the cable into the OTG Adapter.

3. Plug the OTG end of the adapter into the tablet. Make sure to power on the keyboard when you're ready to play.

4. Once the tablet detects the keyboard, you will see a pop up saying Keyboard Connected!.

5. Tap on Settings in the lower left corner.

6. Then tap on Piano from the menu on the left hand side. Select your keyboard model from the dropdown menu.

By connecting your keyboard to your tablet with the necessary cable and adapter, Playground will then be able to recognize the keys you play on your keyboard and offer real-time feedback.

1. To connect the keyboard using a MIDI to USB cable, plug the MIDI IN end of the cable into the MIDI OUT port on the keyboard. Plug the MIDI OUT end of the cable into the MIDI IN port on the keyboard. (If plugging the cables in the above manner doesn't establish a connection, reverse the cables).

2. Plug the USB A end of the cable into the OTD adapter.

3. Plug the OTD end of the adapter into the tablet.

4. Once the app detects the keyboard, you will see a pop up saying Keyboard Connected!.

5. Tap on Settings in the lower left corner.

6. Then tap on Piano from the menu on the left hand side. Select your keyboard model from the dropdown menu.
